The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, a straw cutting apparatus 100 according to a preferred embodiment of the present invention includes a base 110, a feeding assembly 120 and a cutting assembly 130.

The frame 110 is used for supporting and may be a frame structure or a closed hollow structure. The base 110 is provided with a feeding station and a cutting station. The feed and cutting stations are generally spaced apart on the base 110. As shown in fig. 1, the left side of the base 110 is a cutting station and the right side is a feeding station.

The feeding assembly 120 and the cutting assembly 130 are respectively disposed on the feeding station and the cutting station. The feed assembly 120 is used to feed the cryopreserved tubules 10 to a cutting station where the cutting assembly 130 cuts them into a plurality of shorter straws 20. As shown in fig. 1 and 3, the cryopreservation tubule 10 has a hollow circular tubular structure, the straw 20 has a semicircular groove structure, and one end of the straw has a ring structure 21.

Specifically, in the embodiment, the base 110 has a plurality of parallel feeding stations and a plurality of parallel cutting stations, and the plurality of feeding assemblies 120 and the plurality of cutting assemblies 130 are respectively located at the plurality of feeding stations and the plurality of cutting stations.

Adjacent feed assemblies 120 and adjacent cutting assemblies 130 do not interfere with each other. Therefore, a plurality of cryopreserved tubules 10 may be cut at the same time, thereby significantly improving the efficiency of straw 20 processing. As shown in fig. 2, the feeding station and the cutting station are 5, and correspondingly, the feeding assembly 120 and the cutting assembly 130 are 5. Therefore, 5 cryopreserved tubules 10 may be cut simultaneously.

The feeding assembly 120 performs a gap feeding motion at a preset frequency to feed the cryopreservation tubule 10 to the cutting station. Each movement of the cryopreservation tubule 10 by the feeding assembly 120 is referred to as a feeding cycle. At the interval of two feed cycles, the cutting assembly 130 is activated to cut the cryopreserved tubule 10. Thus, each time a feed cycle is completed, one straw 20 is obtained.

Since the distance the feed assembly 120 is fed is constant during each feed cycle. Therefore, the lengths of the plurality of straws 20 finally cut are also kept uniform.

In the present embodiment, the feeding assembly 120 includes an adjusting plate 125, and the adjusting plate 125 is used for adjusting the step length of the gap feeding movement of the feeding assembly 120.

That is, by adjusting the dial 125, the distance the feed assembly 120 is fed in each feed cycle may be adjusted. Therefore, the moving distance of the freezing tubule 10 in each feeding period can be adjusted, and finally the size of the straw 20 can be adjusted to obtain straws 20 with different specifications.

In this embodiment, the feeding assembly 120 includes a storage bin 121 having a conveyor 123, the storage bin 123 having an input port 1232 and an output port (not shown), and the conveyor 123 has a surface opposite to the output port and extends from the feeding station to the cutting station.

Specifically, the storage bin 123 is generally disposed along a vertical direction, and the discharge port faces the bottom of the base 110. A plurality of freezing tubules 10 can be temporarily stored in the storage bin 123. Therefore, the straw cutting apparatus 100 can be maintained in operation for a long time by one feeding. After one freezing tubule 10 is cut, the next freezing tubule 10 in the storage bin 123 can fall to the surface of the conveyor belt 123 under the action of gravity, and automatic feeding is achieved.

The cutting assembly 130 includes a first blade 131, a second blade 132, and a third blade 133. Wherein, the first blade 131 is disposed on the feeding path of the feeding assembly 120 and is used for cutting the cryopreservation tubule 10 along the central axis thereof. The central axis refers to an axis passing through the center of the cryopreservation tubule 10 and coinciding with the extending direction thereof. Thus, the first blade 131 may cut the cryopreserved tubule 10 into two semi-circular groove structures. The first blade 131 can be fixedly installed, and the frozen tubule 10 and the first blade 131 can move relatively under the action of the feeding assembly 120, so as to realize cutting.

The second and

third blades

132 and 133 are spaced apart from each other in the feeding direction of the feeding assembly 120, and are used to cut the cryopreservation tubule 10 in a direction perpendicular to the central axis thereof. The second blade 132 and the third blade 133 are located between the first blade 131 and the feeding assembly 120. That is, as shown in fig. 1, the second blade 132 and the third blade 133 are located at the right side of the first blade 131.

And also. The second blade 132 is located on a side of the third blade 133 facing the feeding assembly 120. The second blade 132 and the third blade 133 can cut the cryopreserved tubule 10 by extension and contraction. Specifically, in the present embodiment, the second blade 132 and the third blade 133 are movable in a first direction (i.e., up and down direction shown in fig. 1) perpendicular to the feeding direction of the feeding assembly 120 to cut the cryopreservation tubule 10. In addition, the second blade 132 and the third blade 133 can exhibit different cutting effects by controlling the cutting depth. Specifically, the second blade 132 may cut off the cryostraw 10, and the third blade 133 may cut the central axis of the cryostraw 10. That is, the third blade 133 can cut only half of the cryopreserved tubule 10.

After the third blade 133 cuts, the semicircular groove of the upper half part cut by the first blade 131 can be cut. Furthermore, since the first blade 131 does not exceed the cutting sites of the second blade 132 and the third blade 133, the part of the cryopreserved tubule 10 between the second blade 132 and the third blade 133 is retained, thereby obtaining the ring-shaped structure 21 at the end of the straw 20. By sequentially cycling through a plurality of feeding cycles, the frozen tubule 10 can be cut to complete the cutting and obtain a plurality of straws 20.

The length of the straw 20 obtained by cutting is determined by the distance of movement of the cryopreserved tubule 10 in each feeding cycle. Since the distance of each advance of the feeding assembly 120 is fixed. Moreover, since the position of each blade is fixed, the size of the straw 20 obtained by cutting a plurality of times can be kept uniform.

In this embodiment, a removable collection cassette 140 is provided at the cutting station.

Specifically, the collecting box 140 may be mounted on the base 110 by plugging, and when the collecting box 140 needs to be taken out, the collecting box 140 may be pulled out from the base 110. The collection box 140 may be an open-ended box-like structure, and is generally located at the bottom of the housing 110. When the straw 20 is obtained by cutting the freezing tubule 10 by the second blade 132, the straw 20 can fall into the collection box 140 by gravity, so that the straw 20 can be conveniently collected.

Further, in this embodiment, the cutting station is further provided with a bearing plate 141 opposite to the second blade 132, and the second blade 132 can move to abut against the bearing plate 141.

Specifically, the carrier plate 141 may be disposed at an edge of the collection box 140, and is bent and formed by the edge of the collection box 140. When the second blade 132 performs cutting, the bearing plate 141 can provide a supporting function for the second blade 132, which is equivalent to a "chopping board", so that the second blade 132 can rapidly cut off the cryopreservation tubule 10.

In this embodiment, a carrying rod 150 for fixing the cryopreservation tubule 10 is further disposed on the cutting station, and the first blade 131 is disposed at the end of the carrying rod 150.

In particular, the carrier rod 150 may provide support to the cryopreserved tubule 10 such that the cryopreserved tubule 10 may remain stable during cutting by the cutting assembly 130. When the feeding assembly 120 drives the cryopreservation tubule 10 to feed to the cutting station, one end of the cryopreservation tubule 10 can be limited by the carrying rod 150. The carrying rod 150 can fix one end of the cryopreservation tubule 10 in a clamping, sleeving and other modes.

Further, in this embodiment, the carrying rod 150 is a hollow tubular structure with two open ends, the cryopreservation tubule 10 can be inserted into the carrying rod 150, the base 110 is provided with a first recovery box 113, and the first recovery box 113 is located at one end of the carrying rod far from the first blade 131.

Therefore, when the upper semicircular groove is cut by the third blade 133, the cut portion can slide down into the first recovery box 113 through the inside of the carrying bar 150, thereby separating the waste material from the straw 20.

Further, in this embodiment, the conveyor belt 123 can rotate forward and backward, the base 110 is provided with a second recycling box 115, and the second recycling box 115 is located at an end of the conveyor belt 123 far away from the cutting station.

Specifically, the conveyor 123 may feed the cryopreserved tubules 10 to the cutting station. However, since the cryopreserved tubule 10 is cut a plurality of times, the end portion thereof cannot be processed and becomes waste. At this time, the conveyor 123 is reversed to convey the waste material to the second recovery box 115, thereby preventing the waste material from being mixed with the desired straw 20.

According to the straw cutting device 100, when the cryopreservation tubule 10 is driven by the feeding assembly 120 to feed to the cutting station, the first blade 131 can cut the cryopreservation tubule 10 from the middle along the central axis. After one feeding cycle, the second blade 132 and the third blade 133 perform cutting. Wherein, the third blade 133 can partially cut the frozen tubule and the second blade 132 can cut the frozen tubule by matching with the first blade 131. Further, a portion of the cryopreserved tubule between the second blade 132 and the third blade 133 is retained, thereby obtaining a wedge-shaped straw 20. Then, the next feeding cycle is performed and the circulation is performed in sequence, thereby obtaining a plurality of straws 20. The feeding assembly 120 and the cutting assembly 130 automatically cut the frozen tubule 10 to obtain straws without depending on manual operation. Moreover, the distance of each feeding of the feeding assembly 120 is fixed, and the cutting position of each blade is fixed, so that the sizes of straws 20 obtained by multiple cutting can be kept consistent. Therefore, the straw cutting device 100 is not only convenient to operate but also can improve the quality of the straw 20.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
